In Silico Studies and In Vivo MAOA Inhibitory Activity of Coumarins Isolated from Angelica archangelica Extract: An Approach toward Antidepressant Activity.

ABSTRACT: The current investigation was aimed at in vivo MAOA inhibitory activity of coumarins angelicin, bergapten, and scopoletin isolated from the roots of Angelica archangelica. The isolated compounds were screened for MAOA (pdb ID 2Z5y) binding through molecular docking studies. The molecular docking results displayed that bergapten has a maximum affinity for MAOA, followed by angelicin and scopoletin. In silico prediction of physicochemical parameters indicated that maximum blood-brain barrier (BBB) permeability was observed with angelicin (2.3), followed by bergapten (2.0) and least with scopoletin (0.644). In consonance to the results of molecular docking studies, appreciable in vivo antidepressant activity of angelicin and bergaptan was observed over the mouse model of reserpine-induced depression. The modulation of MAOA in the antidepressant effect of extract and its isolated fractions was also determined. Biochemical examination of the brain tissue indicated that bergapten has maximum MAOA inhibitory activity while scopoletin fails to inhibit brain MAOA.
